This invention relates to screens, and more particularly to door andwindow screens of the roll type.

The primary ob of the invention is the character which will iect or dooropening with which the screen will be fully invention is to provide ascreen of this character including guide strips arranged at windowopening,

Referring to the drawings in detail, the reference character 5designates the metallic window frame, within which the window screen,formingthe subject matterof the invention is positioned. I

In the present showing, the housing in which the window screen isrolled, is mounted at the upper end of the window frame, however it iserence character 6, is of a length to extend between the side rails of awindow or door frame, as clearly shown by Fi ure 1 of the drawings, thehousing being rectangular in formation. The ends of the housing areclosed by means of the end plates 7, that are so constructed that theyfit within the open ends of the housing, where they are bolted orotherwise secured in position.

The housing is formed with a longitudinal slot in the underside thereofthrough which the wire mesh material of which the screen is formed, andto be hereinafter more fully described, passes into the housing. 7

These ends plates 7 are formed with depending flanges 8 that affordmeans whereby the housing may be secured inposition between the siderailsof the w ndow or door frame with which the device is used. i

The roller on which the wire. mesh material of the screen is wound, isindicated by the reference character 9, and is mounted in suitablebearings mounted in the plates 7.

Secured to the side members of the window frame, are guide rails 26which are formed by pressing a length of sheet metal material in such away as to provide spaced walls 27 that have longitudinal recessedportions 28 defining parallel ribs 29, the outer edges of the spacedwalls being turned inwardly as at 30, providing a smooth surface forcontact with the wire mesh material of the screen.

In the construction of these guide rails, longitudinal flanges 31 areprovided, which flanges are provided with openings to receive securingscrews to permit the guide rails to be secured in position within awindow frame.

or H

together without the use The upper ends of these guide rails are open,the lower endstherepf being closed by means of the keepers 32 that areformed with end pieces 33 which contact with the lower ends of the guiderails closing the lower ends of the guide rails.

This construction permits of the ready removal of the keepers, should itbe desired to cut the side rails in fitting the side rails within aWindow frame. The free end of the wire mesh material 17, is secured tothe lift rail 34 by means ofthe spline 35 that fits within the clamp36,, which embodies a length of sheet metal material bent upon itselfproviding side members 37, which are held under the inturned ends 38 ofthe lift rail.

The construction of the lift rail is such that grooves 39 are formed inthe outer surfaces thereof, providing ribs 40 that provide guides forthe spring fingers 41 of the guidepieces or shoes 42, which are curvedto fit within the ends of the lift rail, the curved walls of the liftrails and curvatures of the fingersinsuring a close fit between'thefingers and lift rail.

Should it be desirable to reverse the lift rail, to provide a clearancefor sash hardware or other obstructions, this may be readilyaccomplished by removing the guide pieces 42 from the ends of the liftrail 34. Tnewire clamps 36 and spline 35,

- and wire 1'7, are now readily removed.

After the lift rail has been reversed, the wire cloth is positioned inthe lift rail and the shoes or guide pieces are positioned in the endsof the lift rail.

These guide pieces 42 are formed with elongated heads 43 which whenpositioned within the guide rails, contact with the parallel ribs 29 toinsure against lateral movement of the lift rail. c

As clearly shown by Figure 8 of the drawings, the lift rail comprisestwo lengths of sheet metal material bent to provide longitudinal groove44 for the reception of the contact felt 45, one wall of the groovebeing formed with spurs 46 that are embedded in the felt to hold thefelt in position Within the groove of the lift rail. A flange 44'extends inwardly from the lift rail and is formed with an inturnedflange 45 closely engaging the flange 46', of one of the lengths ofsheet metal of the lift rail. 7

Thus it will be seen that due to this construction, the side members ofthe lift rail are held of rivets, bolts or similar securing means.

The lift rail 34 being hollow, provides a housing for the sliding bolts47 that extend through openings in the guide pieces 42, where theyproject beyond the outer edges of the guide pieces and pass into theguide rails 26 for engagement with the keepers 32.

When the bolts 4'? are in engagement with the keepers 32, the coiledspring 22 is held under having open tension, to rewind the wire meshmaterial on the screen roller, when the sliding bolts are released ordisengaged from the keepers.

The inner ends of the sliding bolts 4'7 are reduced to receive thesprings 48 which have their inner ends positioned against the stop 49that is secured within the lift rail, at a point intermediate the endsthereof. Secured to the sliding bolts 47 are finger pieces 50 that passthrough openings in the lift rail, and extend to positions where theymay be readily grasped by the operator to compress the springs 48 andretract the sliding bolts 47.

A'modified form of guide to be used in conjunction with a plaster lambsocket is shown by Figure 14 of the drawings. The socket portioncomprises a length of sheet metal material bent upon itself to providespaced double walls defining a groove or guideway 51, to receive theextension 52 formed on the guide member 53. This form of guide rail'andplaster jamb socket is especially adapted for application-to plasterside jambs, and provides a yieldable connection between the extensions52 and guideway 51. In this form of 54 are provided, which flangespresent fiat surfaces to be embedded in the plaster of which the jamb isformed.

From the foregoing itwill be seen that we have provided a metallicwindow screen which may be readily assembled or disassembled, thevarious elements of the screen being secured together by frictionalcontact, thereby eliminating the use of bolts, rivets, solder or othersimilar securing means commonly used in metallic screen cona struction.
